Simplified Mathematical Model

A high speed camera was used for interferometry visualization (in different phases of the motion) of the fluttering NACA0015 profile supported in a translational and rotational manner. First, the simplified mathematical model of the support of investigated profile was identified from minimum least squares differences between modeled and measured system responses. A special graphical Matlab procedure was proposed for evaluation of interferograms. Kinematic analysis defining motion of the profile as a function of time was obtained by a regression using the least squares method. Numerical integration of pressure functions around the airfoil surface allows for calculation of the resulting aerodynamic forces and moments.

Simplified Mathematical Model

The high-speed spinning bell electrostatic automatic machine is the key equipment of the automotive coating line. A simplified mathematical model of the process of spraying aggradation was proposed by analyzing the working principle of electrostatic spray. Furthermore, the relationships among spraying distance, spraying speed and number of spraying pattern overlap were investigated and revealed. And the expressions for the velocities of both side spraying machine and top spraying machine are derived. This work provides an important theoretical basis for the spraying trajectory planning .

High Speed Machine

The assessment of the limiting state of high-speed machine-manual taps in the processing of structural steel billets is considered. A general multi-parameter dependence is developed for calculating the criterion of allowable wear, which makes it possible to rationally use the tool life and normalize the cut amount during regrinding.
